Then why wasn’t a flight attendant called in to be with the sick one?
Could have been a sudden heart attack.
I am not saying that a flight attendant was called in because the pilot is sick...it is standard operating procedure to have a flight attendant stand in the cockpit while a pilot leaves the cockpit for any reason. It’s a safety procedure in the event the single pilot in the cockpit has a medical issue while the other pilot is using the restroom, etc. I am wondering first why the pilot left the cockpit...may to use the restroom? At that point a flight attendant would have been placed in the cockpit.
There is no evidence that one was sick.
